mrf1517 application notes
hi,everyone.
I got the job to design a PA at 400MHz, with P1dB>4W,the Vd<12.5V.
I have searched many many datasheets such as Minicircuits,triquint, as well as
freescale,philips,infeon and so on.But I can't find a good module or a discrete transistor.
Since the key requirement is that the required size of the PA <5cm.
but some mosfet such as MRF1518T,MRF1517,ne5511279a's typical application
circuits are all using transmision line to macth. because @400MHz,the λ is very long,so
the size cannot be small.
could any one introduce some methods or some transistors or modules to me ?
great thanks!
Best Regards!!
